John told his daughter that he was driving to the hospital. Then he lost his vision — and started to act strangely.

"He told me he couldn't see, and started panicking, saying, 'I don't know what to eat, I don't know what to eat," Esteria recalled. "Then, he gave me his phone, but didn't tell me what to do! I didn't know if I needed to call the ambulance or what I needed to do!"

She reached over her father and grabbed the steering wheel from the backseat with one hand.

"He was fighting me, and I couldn't make the turns that I needed to do," she said. "I hit a curve, and we almost ran into the front of an ambulance!"

The young girl drove the vehicle about eight blocks to the ER. By that time, John had lost his vision, motor skill and memory.

"She was still a trooper," Tia Smith, Esteria's mom, toldWJHG. "She was still by his bedside. It was not the best of conditions, another child would have probably panicked and continued to panic — she didn't. She gave me a report, told me what happened, and gave the nursing staff his health history that she did know."

Doctors discovered a tumour the size of a golf ball on the left side John's brain. He's now receiving treatment.
